Description

Technical Field

[0001] This utility model relates to the field of electric height-adjustable desks, and in particular to electric height-adjustable desks. Background Technology

[0002] Existing electric height-adjustable desks on the market include a tabletop, two height-adjustable legs for supporting the tabletop, and a controller. Each height-adjustable leg includes a height-adjustable column and feet installed at the bottom of the column. The controller is located on the bottom surface of the tabletop between the two height-adjustable legs. The height-adjustable column includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a motor connected to the transmission assembly. The motor is connected to a motor control line connected to the controller. The sleeve assembly has feet at one end and a base box connected to the tabletop at the other. A cable axially passes through one of the sleeve assemblies, with one end leading out from the base box and connected to the controller. The other end of the cable leads out from the rear of the sleeve assembly and connects to a power line. By connecting to an external power source via the power line, the height-adjustable legs can be connected to the power grid, allowing the controller to supply power to the motor and control its operation, thereby controlling the extension and retraction of the height-adjustable legs to control the tabletop's height.

[0003] The existing base box and sleeve assembly form an L-shaped column. After the lifting table legs and tabletop are assembled, the base box extends from the sleeve assembly to the other lifting table leg. The base box only has a cable outlet on the side facing the controller for cables and motor control lines to pass through. As a result, taking the lifting table leg with cables installed on the left side of the tabletop as an example, if the external power supply is closer to the right side of the lifting table leg, the lifting table leg with cables needs to be installed on the right side of the tabletop. In order to extend the base box towards the controller, the lifting table leg with cables needs to be rotated 180 degrees and placed on the right side of the tabletop. This results in the cables being led out through the sleeve assembly and facing the user side, which is not only unsightly but also increases the risk of the user's legs getting caught on the power cord, causing it to disconnect or break. In addition, since the power cord needs to be routed to the rear to connect to the external power supply, there will be situations where the power cord cannot be connected to the external power supply due to its limited length, affecting the user experience. Utility Model Content

[0004] To address the shortcomings and deficiencies of the existing technology, this utility model provides an electric height-adjustable table that allows the two table legs to be swapped by translation without changing the direction of the power cord, thus bringing the power cord closer to the external power source and improving the user experience.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] An electric height-adjustable desk includes a tabletop, two height-adjustable legs spaced apart along a first direction, a cable housed within one of the height-adjustable legs, and an external power cord. Each height-adjustable leg includes a height-adjustable column and feet. The height-adjustable column includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a motor connected to the transmission assembly. The motor is connected to a motor control line. The sleeve assembly has feet at one end and a base box connected to the tabletop at the other. The cable axially passes through one of the sleeve assemblies, with one end extending from the base box and the other end connected to the power cord. The base box has a first sidewall and a second sidewall spaced apart along the first direction. The sleeve assembly has a first split surface perpendicular to the first direction. The first and second sidewalls are symmetrical about the first split surface. Both the first and second sidewalls have cable exit holes.

[0007] In the above-mentioned electric height-adjustable table, the length direction of the base is perpendicular to the first direction, the base box is a rectangular box extending along the length direction of the base, and the first side wall and the second side wall form the long side of the rectangular box.

[0008] In the aforementioned electric lifting table, the sleeve assembly has a second dividing surface extending along a first direction, the first sidewall being symmetrical about the second dividing surface, and the second sidewall being symmetrical about the second dividing surface.

[0009] In the aforementioned electric lifting table, the sleeve assembly has a second split surface extending along a first direction, and the first sidewall and the second sidewall are located on the same side of the first split surface.

[0010] In the aforementioned electric height-adjustable desk, the base box includes two third sidewalls extending along a first direction, the first sidewall and the second sidewall are connected between the two third sidewalls, the bottom surface of the desk is provided with a support frame, and the third sidewalls are connected to the support frame.

[0011] In the aforementioned electric lifting table, the third side wall is provided with fixing holes and fasteners connected to the fixing holes. The fixing holes are symmetrical about the first center dividing surface. The support frame is provided with a locking groove. The fasteners are connected to the locking groove to fix the bottom box on the support frame.

[0012] In the aforementioned electric lifting table, the motor is located inside the base box.

[0013] In the above-mentioned electric height-adjustable desk, the electric height-adjustable desk also includes a controller located between the two height-adjustable desk legs. The motor control lines of the two height-adjustable desk legs are electrically connected to the controller, and one end of the cable passing through the top wire hole is electrically connected to the controller.

[0014] In the aforementioned electric height-adjustable desk, one end of the power cord and cable connection is located outside the base, and the base is provided with a decorative cover that covers the power cord and cable connection end, with a bottom cable outlet hole on the rear side of the decorative cover.

[0015] In the aforementioned electric lifting table, one side of the sleeve assembly is provided with an interface, the other end of the cable is electrically connected to the interface, and one end of the power cord is provided with a first plug that is plugged into the interface.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] 1. In this utility model, the cable passes through the axial direction inside the sleeve assembly, achieving concealed wiring, avoiding the mess of exposed cables, and improving aesthetics. In addition, the base box has a first side wall and a second side wall spaced apart along a first direction, and the sleeve assembly has a first split surface perpendicular to the first direction. The first side wall and the second side wall are symmetrical about the first split surface. This design allows the base box to form a symmetrical structure along the first direction, thus making the base box adaptable to two installation positions. This allows the two lifting table legs to be interchanged by translation. Especially when the power cord is led out from the rear side of the lifting column, the direction of the power cord will not be changed after the position is interchanged by translation, so that the power cord is closer to the external power source, improving the user experience. Both the first side wall and the second side wall are provided with top cable outlet holes. Compared with the single-sided cable outlet of the base box in the prior art, the base box in this embodiment can achieve double-sided cable outlet. After the position of the lifting table legs is interchanged, the direction of the motor control line and the cable outlet can be adjusted by switching the top cable outlet holes, thereby adapting to the adjusted position. Taking the first direction as left and right as an example, with the first sidewall on the right and the second sidewall on the left, if the lifting table leg with cables is installed on the left side of the tabletop, the motor control line and cable on the left side will be led out to the right through the top-out cable hole on the first sidewall and connected to the controller. The motor control line of the lifting table leg on the right side will be led out to the left through the top-out cable hole on the second sidewall and connected to the controller. If the external power supply is closer to the right lifting table leg, the two lifting table legs can be moved and swapped. At this time, the motor control line and cable on the lifting table leg with cables can be led out to the left through the top-out cable hole on the second sidewall and connected to the controller, while the motor control line on the lifting table leg without cables will be led out to the right through the top-out cable hole on the first sidewall and connected to the controller. This allows the direction of the motor control line and cable to be adjusted even after the two lifting table legs are moved and swapped, without the need for winding. This makes the routing of the motor control line and cable more aesthetically pleasing, allowing users to freely adjust the position of the lifting table legs according to the location of the external power supply, thereby improving the user experience.

[0018] 2. The length direction of the base is perpendicular to the first direction, and the base box is a rectangular box extending along the length direction of the base. The first side wall and the second side wall form the long side of the rectangular box. This design simplifies the processing and forming of the base box; in addition, it avoids the base box extending along the first direction from occupying the space under the tabletop used to accommodate the user's legs, thus making the space under the tabletop larger and improving the user experience.

[0019] 3. The sleeve assembly has a second split surface extending along the first direction, the first sidewall is symmetrical about the second split surface, and the second sidewall is symmetrical about the second split surface. This design allows the lifting column to form a T-shaped column, thereby improving the stability of the base box in supporting the tabletop and facilitating the subsequent fixed connection between the base box and the tabletop.

[0020] 4. The sleeve assembly has a second split surface extending along a first direction, and the first sidewall and the second sidewall are located on the same side of the first split surface. With this design, after assembly, by positioning the base box behind the lifting column, the space under the tabletop in front of the lifting column can be increased, thus preventing the base box from interfering with the user's legs and improving the user experience.

[0021] 5. The base box includes two third sidewalls extending along the first direction. The first and second sidewalls are connected between the two third sidewalls. A support frame is provided on the bottom surface of the tabletop, and the third sidewalls are connected to the support frame. This design allows the part where the base box connects to the support frame to be staggered from the top cable outlet hole, thus avoiding interference between the motor control lines or cables and the connection between the base box and the support frame.

[0022] 6. The third side wall is provided with fixing holes and fasteners that connect to the fixing holes. The fixing holes are symmetrical about the first split surface. The support frame is provided with locking slots, and the fasteners slide into the locking slots and connect with them. With this design, after the two lifting table legs are swapped in position by translation, it can still ensure that the fasteners on the bottom box after the swap are connected to the locking slots at that position. There is no need to set multiple locking slots on the support frame to accommodate the swapped bottom boxes, thus reducing the manufacturing difficulty of the support frame. In addition, by having the fasteners slide into the locking slots and connect with them, the disassembly and assembly of the bottom box can be made simpler and more convenient.

[0023] 7. The motor is located inside the base box. Compared to placing the motor inside the sleeve assembly, utilizing the space inside the base box to accommodate the motor reduces the size of the sleeve assembly, making the lifting column more compact.

[0024] 8. The end of the power cord and cable connection is located on the outside of the base. A decorative cover is provided on the base to cover this end, with a bottom cable exit hole on the back of the cover. This design provides physical protection for the power cord and cable connection, such as protection against kicks, dust, and liquid splashes, preventing users' legs from hitting the connection and causing a short circuit or even damage. Furthermore, excess power cord can be stored inside the cover, reducing the probability of the user's legs snagging on the cord.

[0025] 9. One side of the sleeve assembly has an interface, and the other end of the cable is electrically connected to the interface. One end of the power cord has a first plug that connects to the interface. This design facilitates the replacement of the power cord separately in the future, reducing maintenance costs.

Detailed Implementation

[0037] This utility model provides an electric height-adjustable desk, including a tabletop, two height-adjustable legs spaced apart along a first direction, a cable disposed within one of the height-adjustable legs, and an external power cord. Each height-adjustable leg includes a height-adjustable column and feet. The height-adjustable column includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a motor connected to the transmission assembly. The motor is connected to a motor control line. The sleeve assembly has feet at one end and a base box connected to the tabletop at the other. The cable axially passes through one of the sleeve assemblies, with one end extending from the base box, and the other end connected to the power cord. The base box has a first sidewall and a second sidewall spaced apart along the first direction. The sleeve assembly has a first split surface perpendicular to the first direction. The first and second sidewalls are symmetrical about the first split surface. Both the first and second sidewalls have cable outlet holes.

[0038] In this invention, the cable passes axially through the inside of the sleeve assembly, achieving concealed wiring, avoiding the clutter of exposed cables, and improving aesthetics. Furthermore, the base box has a first sidewall and a second sidewall spaced apart along a first direction, and the sleeve assembly has a first split surface perpendicular to the first direction. The first and second sidewalls are symmetrical about the first split surface. This design allows the base box to form a symmetrical structure along the first direction, enabling it to adapt to two installation positions. This allows the two lifting table legs to be interchanged simply by translation. Especially when the power cord is led out from the rear of the lifting column, the direction of the power cord's lead-out remains unchanged after the position is interchanged, bringing the power cord closer to the external power source and improving the user experience. Both the first and second sidewalls have top-out cable holes. Compared to the single-sided cable exit of existing base boxes, the base box in this embodiment can achieve double-sided cable exit. After the lifting table legs are interchanged, the direction of the motor control cable and the cable exit can be adjusted by switching the top-out cable holes, thus adapting to the adjusted position. Taking the first direction as left and right as an example, with the first sidewall on the right and the second sidewall on the left, if the lifting table leg with cables is installed on the left side of the tabletop, the motor control line and cable on the left side will be led out to the right through the top-out cable hole on the first sidewall and connected to the controller. The motor control line of the lifting table leg on the right side will be led out to the left through the top-out cable hole on the second sidewall and connected to the controller. If the external power supply is closer to the right lifting table leg, the two lifting table legs can be moved and swapped. At this time, the motor control line and cable on the lifting table leg with cables can be led out to the left through the top-out cable hole on the second sidewall and connected to the controller, while the motor control line on the lifting table leg without cables will be led out to the right through the top-out cable hole on the first sidewall and connected to the controller. This allows the direction of the motor control line and cable to be adjusted even after the two lifting table legs are moved and swapped, without the need for winding. This makes the routing of the motor control line and cable more aesthetically pleasing, allowing users to freely adjust the position of the lifting table legs according to the location of the external power supply, thereby improving the user experience.

It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description.

[0040] Example 1

[0041] Combination Figures 1 to 9As shown, the electric height-adjustable desk of this utility model includes a tabletop 100, two height-adjustable table legs 200 spaced apart along a first direction, a cable 300 disposed within one of the height-adjustable table legs 200, and an external power cord 400. Each height-adjustable table leg 200 includes a height-adjustable column 210 and feet 220. The height-adjustable column 210 includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a motor connected to the transmission assembly. The motor is connected to a motor control line 500. The feet 220 are respectively provided at both ends of the sleeve assembly. The bottom box 600 is connected to the tabletop 100. The cable passes through one of the sleeve assemblies axially and one end is led out from the bottom box 600. The other end of the cable is connected to the power cord 400. The bottom box 600 has a first side wall 610 and a second side wall 620 spaced apart along a first direction. The sleeve assembly has a first dividing surface O1 perpendicular to the first direction. The first side wall 610 and the second side wall 620 are symmetrical about the first dividing surface O1. Both the first side wall 610 and the second side wall 620 are provided with a top cable hole 601.

[0042] In this embodiment, the cable 300 passes through the axial direction inside the sleeve assembly, achieving concealed wiring, avoiding the clutter of exposed cables 300, and improving aesthetics. Furthermore, the base box 600 has a first sidewall 610 and a second sidewall 620 spaced apart along a first direction. The sleeve assembly has a first dividing surface O1 perpendicular to the first direction. The first sidewall 610 and the second sidewall 620 are symmetrical about the first dividing surface O1. This design allows the base box 600 to form a symmetrical structure along the first direction, enabling it to adapt to installation in two positions. This allows the two lifting table legs 200 to be moved by translation. The positions can be interchanged, especially when the power cord 400 is led out from the rear of the lifting column 210. After the positions are interchanged by translation, the direction of the power cord 400 will not be changed, so that the power cord 400 is closer to the external power source, improving the user experience. Both the first side wall 610 and the second side wall 620 are provided with top cable outlet holes 601. Compared with the single-sided cable outlet of the bottom box in the prior art, the bottom box 600 in this embodiment can realize double-sided cable outlet. After the positions of the lifting table legs 200 are interchanged, the direction of the motor control line 500 and the cable 300 can be adjusted by switching the top cable outlet holes 601, so as to adapt to the adjusted position.

[0043] In addition, the electric lifting table in this embodiment also includes a controller 700 located between the two lifting table legs 200. The motor control lines 500 of the two lifting table legs 200 are electrically connected to the controller 700, and one end of the cable 300 passing through the top wire hole 601 is electrically connected to the controller 700.

[0044] In this embodiment, the first direction is the left-right direction, so the first dividing surface O1 extends along the front-back direction, and the left and right sides of the sleeve assembly are symmetrical about the first dividing surface O1. Furthermore, the first sidewall 610 is defined as being on the right, and the second sidewall 620 as being on the left. Figures 1 to 3 As shown, the lifting table leg 200 with cables is installed on the left side of the tabletop 100. The motor control line 500 and cable 300 on the left side are led out to the right through the top-out cable hole 601 on the first side wall 610 and connected to the controller 700. Figure 1 , Figure 5 and 6 As shown, the motor control line 500 of the right-side lifting table leg 200 is led out to the left through the top-out cable hole 601 on the second side wall 620 and connected to the controller 700. If the external power supply is located closer to the right-side lifting table leg 200, the two lifting table legs 200 are moved and interchanged. At this time, the motor control line 500 and cable 300 on the lifting table leg 200 with cables can be led out to the left through the top-out cable hole 601 on the second side wall 620 and connected to the controller 700. The lifting table leg 200 without cables... The motor control line 500 on the table leg 200 is led out to the right through the top cable hole 601 on the first side wall 610 and connected to the controller 700. This allows the direction of the motor control line 500 and cable 300 to be adjusted after the two lifting table legs 200 are moved and swapped, without the need for winding. This makes the wiring of the motor control line 500 and cable 300 more aesthetically pleasing. In other words, users can freely adjust the position of the lifting table legs 200 according to the location of the external power supply, thereby improving the user experience.

[0045] In this embodiment, the specific structure of the lifting column 210 can be referenced from the existing technology CN221599451U. That is, the cable 300 is spiral-shaped. When the lifting column 210 extends, the pitch of the cable 300 increases to lengthen the whole structure. When the lifting column 210 shortens, the pitch of the cable 300 decreases to retract the whole structure. Therefore, the cable 300 will extend and retract with the extension and retraction of the lifting column 210.

[0046] The sleeve assembly in this embodiment includes an inner tube 211, a middle tube 212, and an outer tube 213, which are sequentially sleeved from the inside out. Unlike the prior art CN221599451U, in this embodiment, the bottom of the inner tube 211 is fixedly connected to the foot 220. The bottom of the inner tube 211 has a cable outlet located above the foot 220. The upper end of the cable 300 is led out through the top cable outlet hole 601, and the lower end of the cable 300 is connected to the power cord 400 through the cable outlet. In this embodiment, the cable outlet is an interface with a terminal block. The cable 300 is electrically connected to the lower end of the cable within the inner tube 211, thus achieving electrical connection between the cable 300 and the interface. The inner tube 211 also contains an overload protection structure, which is electrically connected to the terminal block of the live wire. When the current exceeds the limit, the overload protection structure automatically trips, cutting off the circuit and preventing the wire from burning out due to overload. This effectively reduces the risk of equipment damage and personal safety threats caused by short circuits, protecting the lifting column 210 from overload current and ensuring product safety during use. Figure 4 As shown, one end of the power cord 400 in this embodiment is provided with a first plug 410. The first plug 410 is plugged into the interface to achieve electrical connection. This design facilitates the individual replacement of the power cord 400 in the future and reduces maintenance costs.

[0047] like Figure 1 and Figure 4 As shown, the cable outlet is located on the rear side of the inner tube 211, that is, on the side of the inner tube 211 away from the user. This design allows the power cord 400 to be closer to the external power source, improving the user experience. Since the cable outlet is located outside the foot 220, the first plug 410 is exposed, which could easily lead to the user kicking the first plug 410 and causing a circuit break. To avoid this, in this embodiment, the foot 220 is provided with a decorative cover 230 to cover the first plug 410. The decorative cover 230 is fixed to the foot 220 by adhesive, snap-fit, or screw connection. The rear side of the decorative cover 230 is provided with a bottom cable outlet hole 231. This design provides physical protection for the connection between the power cord 400 and the cable 300 through the decorative cover 230, such as protection against kicks, dust, and liquid splashes, preventing users' legs from colliding with the connection between the cable 300 and the power cord 400, which could lead to a circuit break or even damage. In addition, excess power cord 400 can be stored inside the decorative cover 230 to reduce the probability of users' legs getting caught on the cord.

[0048] Furthermore, in this embodiment, the length direction of the foot 220 is perpendicular to the first direction, that is, the length direction of the foot 220 extends along the front and back. The bottom box 600 is a rectangular box extending along the length direction of the foot 220. The first side wall 610 forms the right long side of the rectangular box, and the second side wall 620 forms the left long side of the rectangular box. This design simplifies the processing and forming of the bottom box 600; in addition, it avoids the bottom box 600 extending along the first direction from occupying the space under the tabletop 100 used to accommodate the user's legs, thus making the space under the tabletop 100 larger and improving the user experience.

[0049] Preferably, in this embodiment, the sleeve assembly has a second dividing surface O2 extending along a first direction, that is, the second dividing surface O2 extends in the left-right direction, the first sidewall 610 is symmetrical about the second dividing surface O2, and the second sidewall 620 is symmetrical about the second dividing surface O2. This design allows the lifting column 210 to form a T-shaped column, thereby improving the support stability of the base box 600 on the tabletop 100 and facilitating the subsequent fixed connection between the base box 600 and the tabletop 100.

[0050] Secondly, the base box 600 in this embodiment includes two third sidewalls 630 extending along a first direction. The third sidewalls 630 extend along a left-right direction. The first sidewall 610 and the second sidewall 620 are connected between the two third sidewalls 630. The bottom surface of the tabletop 100 is fixed with a support frame 110 by screws. The controller 700 is mounted on the support frame 110. The support frame 110 includes two side plates 111 extending along a left-right direction, two connecting beams 112 extending along a front-back direction, and a baffle 113 extending along a left-right direction. A connecting beam 112 is connected to the left end of the two side plates 111, and another connecting beam 112 is connected to the right end of the two side plates 111. The length of the baffle 113 is less than the length of the side plates 111. The baffle 113, the two side plates 111, and the table 100 form a cavity to accommodate the controller 700. The end of the baffle 113, together with the adjacent connecting beam 112 and the two side plates 111, forms a mounting cavity 114 to accommodate the bottom box 600. That is, the left and right sides of the support frame 110 are respectively provided with mounting cavities 114 to accommodate the bottom box 600. The third side wall 630 is connected to the side wall of the mounting cavity 114. This design allows the part where the bottom box 600 is connected to the support frame 110 to be staggered from the top cable hole 601, so as to avoid the motor control line 500 or the cable 300 interfering with the connection between the bottom box 600 and the support frame 110, or in other words, the part where the bottom box 600 is connected to the support frame 110 to interfere with the routing of the motor control line 500 or the cable 300.

[0051] like Figure 3 and 4As shown, in order to facilitate the connection between the bottom box 600 and the support frame 110, in this embodiment, each of the two third side walls 630 is provided with a fixing hole 631 and a fastener 632 threadedly connected to the fixing hole 631. The fixing hole 631 is symmetrical about the first split surface O1. The support frame 110 is provided with a locking groove 1110, that is, the side plate 111 is provided with a locking groove 1110. The fastener 632 slides into the locking groove 1110 and is connected to the locking groove 1110. With this design, even after the two lifting table legs 200 are swapped in position by translation, the fasteners 632 on the swapped base box 600 can still be connected to the slots 1110 at that position. There is no need to set multiple slots 1110 on the side plate 111 to accommodate the swapped base box 600, thus reducing the manufacturing difficulty of the side plate 111, which in turn reduces the manufacturing difficulty of the support frame 110. In addition, by having the fasteners 632 slide into the slots 1110 and connect with them, the disassembly and assembly of the base box 600 can be made simpler and more convenient.

[0052] like Figure 9 As shown, the locking slot 1110 in this embodiment includes a guide slot 1111 and a support slot 1112. The guide slot 1111 extends vertically at an angle, and the support slot 1112 extends horizontally. The lower end of the guide slot 1111 is open, and the other end is connected to one end of the support slot 1112. When the bottom box 600 is assembled with the support frame 110, the fastener 632 slides into the guide slot 1111 through the lower end of the guide slot 1111 and is locked into the support slot 1112, so that the support slot 1112 provides support for the fastener 632, so that the bottom box 600 is connected to the support frame 110. When disassembling, the bottom box 600 can be pushed in the opposite direction.

[0053] Finally, in this embodiment, the motor is housed within the base box 600. Compared to housing the motor within the sleeve assembly, utilizing the space inside the base box 600 to accommodate the motor allows for a reduction in the size of the sleeve assembly, making the lifting column 210 more compact.

[0054] It is understood that in other embodiments of this utility model, the motor may also be installed inside the sleeve assembly.

[0055] It is understood that in other embodiments of this utility model, the third sidewall may also be connected to the sidewall of the support frame by screws.

[0056] It is understood that in other embodiments of this utility model, the sleeve assembly has a second split surface extending along the first direction, and the first sidewall and the second sidewall are located on the same side of the first split surface. Preferably, the first sidewall and the second sidewall are located on the rear side of the first split surface. With this design, after assembly, by placing the bottom box on the rear side of the lifting column, the space under the table on the front side of the lifting column can be increased, so as to avoid the bottom box interfering with the user's legs and improve the user's experience.

[0057] It is understood that in other embodiments of the present invention, the sleeve assembly has a second split surface extending along a first direction, and the first sidewall and the second sidewall are both located on the front side of the first split surface; or both the first sidewall and the second sidewall have a portion located on the front side of the first split surface and another portion located on the rear side of the first split surface, and the lengths of the first sidewall and the second sidewall on both sides of the first split surface are not equal.

[0058] It is understood that in other embodiments of this utility model, the bottom box is a rectangular box extending along the width direction of the base, that is, the length of the bottom box extends along the first direction, and the short sides on the left and right sides of the bottom box form the first side wall and the second side wall.

[0059] It is understood that in other embodiments of this utility model, the outlet is a through hole, and one end of the power cord passes through the outlet and is integrally connected with the cable. This design simplifies the connection structure of the power cord and the cable, further reducing manufacturing costs.

[0060] It is understood that in other embodiments of this utility model, the sleeve assembly is inverted so that the outer tube is inserted into the cavity, the outlet is located at the bottom of the outer tube, and the inner tube is fixedly connected to the bottom box.

[0061] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined in the claims of this utility model.
